Applications of neurofeedback training in cognitive rehabilitation / 中华行为医学与脑科学杂志

Cognitive impairment is a common dysfunction after central nervous system disease or injury, which seriously affects the daily life of patients and brings heavy economic burdens to the family and society. Neurofeedback training (NFT) based on electroencephalography (EEG) is a non-invasive method of neuroregulation, which can improve cognitive function and behavior by autonomously adjusting brain function through feedback. This paper reviews the application of EEG signal-based neurofeedback training in cognitive rehabilitation, and discusses the current problems and future development trends in this field, so as to provide new ideas for clinical research and treatment of cognitive disorders.

Objective:To investigate the early clinical effect of fascia lata autograft bridging combined with the long head of biceps tendon transposition for treatment of irreparable massive rotator cuff tear.Methods:All of 31 cases of massive irreparable rotator cuff tear treated in our hospital from March 2016 to March 2020 were analyzed retrospectively. Among them, 17 cases (10 males, 7 females) were repaired with fascia lata autograft bridging under arthroscopy (patch group), the average age was 61.47±6.63 (ranging from 51 to 72) and 14 cases (4 males, 10 females) were repaired with fascia lata autograft bridging combined with the long head of biceps tendon transposition (combined group), the average age was 62.57±6.11 (ranging from 53 to 71). The operation time, intraoperative blood loss, postoperative complications, visual analogue scale (VAS) of pain before operation, at 1 week and 12 months after operation, Constant-Murley score of shoulder joint and American Association of shoulder and elbow Surgeons (ASES) score before operation, at 6 months and 12 months after operation were compared between the two groups. The outcome of rotator cuff healing was evaluated by MRI 1 year after operation.Results:All patients were followed up for 12-27 months (mean 18.33 ±6.8 months). There was no perioperative complication, and there was no significant difference in operation time between the two groups ( P>0.05) . The VAS score in the patch group was significantly higher than the combined group 1 week after operation ( t=2.09, P=0.048) , and there was no significant difference in VAS score 12 months after operation between the two groups. Constant-Murley score and ASES score in the combined group were significantly higher than the patch group at 6 months after operation ( t=5.23, P<0.001; t=4.45, P<0.001) , and there was no significant difference in Constant score and ASES score between the two groups at 12 months after operation. Constant score and ASES score in the two groups were significantly higher than those before operation. One year after operation, the MRI of the affected shoulder showed that the incidence of autograft patch thinning (Sugaya grade III) was 52.94%, the autograft patch structure failure rate (Sugaya grade IV and V) was 17.65% in the patch group, the autograft patch thinning rate (Sugaya grade III) was 35.71%, and the structural failure rate (Sugaya grade IV and V) was 7.14% in the combined group. The difference was statistically significant (χ 2=7.12, P=0.028) . Conclusion:Fascia lata autograft patch bridging combined with long head of biceps tendon transposition technique for treatment of irreparable massive rotator cuff tear has less pain 1 week after operation and better recovery of shoulder function half a year after operation. MRI showed better patch healing 1 year after operation.

Efficacy and clinical outcome of chemotherapy and endocrine therapy as first-line treatment in patients with hormone receptor-positive HER2-negative metastatic breast cancer / 中华医学杂志(英文版)

BACKGROUND@#Endocrine therapy (ET) and ET-based regimens are the preferred first-line treatment options for hormone receptor (HR)-positive and human epidermal growth factor receptor 2 (HER2)-negative metastatic breast cancer (HR+/HER2- MBC), while chemotherapy (CT) is commonly used in clinical practice. The aim of this study was to investigate the efficacy and clinical outcome of ET and CT as first-line treatment in Chinese patients with HR+/HER2- MBC.@*METHODS@#Patients diagnosed with HR+/HER2-MBC between January 1st, 1996 and September 30th, 2018 were screened from the Chinese Society of Clinical Oncology Breast Cancer database. The initial and maintenance first-line treatment, progression-free survival (PFS), and overall survival (OS) were analyzed.@*RESULTS@#Among the 1877 included patients, 1215 (64.7%) received CT and 662 (35.3%) received ET as initial first-line treatment. There were no statistically significant differences in PFS and OS between patients receiving ET and CT as initial first-line treatment in the total population (PFS: 12.0 vs. 11.0 months, P = 0.22; OS: 54.0 vs . 49.0 months, P =0.09) and propensity score matched population. For patients without disease progression after at least 3 months of initial therapy, maintenance ET following initial CT (CT-ET cohort, n = 449) and continuous schedule of ET (ET cohort, n = 527) had longer PFS than continuous schedule of CT (CT cohort, n = 406) in the total population (CT-ET cohort vs. CT cohort: 17.0 vs . 8.5 months; P <0.01; ET cohort vs . CT cohort: 14.0 vs . 8.5 months; P <0.01) and propensity score matched population. OS in the three cohorts yielded the same results as PFS.@*CONCLUSIONS@#ET was associated with similar clinical outcome to CT as initial first-line treatment. For patients without disease progression after initial CT, switching to maintenance ET showed superiority in clinical outcome over continuous schedule of CT.

Mechanism of chlorogenic acid reducing lipopolysaccharide-induced acute lung injury in mice by regulating miR-223/NLRP3 axis / 中南大学学报(医学版)

OBJECTIVES@#Chlorogenic acid has various physiological activities such as antibacterial, anti-inflammatory, and antiviral activities. Studies have shown that chlorogenic acid can alleviate the inflammatory response of mice with acute lung injury (ALI), but the specific mechanism is still unclear. This study aims to investigate whether chlorogenic acid attenuates lipopolysaccharide (LPS)-induced ALI in mice by regulating the microRNA-223 (miR-223)/nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) axis.@*METHODS@#SPF grade BALBc male mice were randomly divided into a control group, a model group, a chlorogenic acid group, a chlorogenic acid+miR-223 negative control (miR-223 NC) group, and a chlorogenic acid+miR-223 inhibitor (miR-223 antagomir) group, 10 mice in each group. Except the control group, the other groups were instilled with 4 mg/kg LPS through the airway to establish the ALI mouse model. After the modeling, the mice in the chlorogenic acid group were continuously given chlorogenic acid (100 mg/kg) by gavage for 7 d. The chlorogenic acid+miR-223 NC group and the chlorogenic acid+miR-223 antagomir group were given 100 mg/kg chlorogenic acid by gavage every day, and then were injected with 10 μL of miR-223 NC (0.5 nmol/μL) and miR-223 antagomir (0.5 nmol/μL) respectively for 7 consecutive days.The control group and the model group were replaced with normal saline. The lung tissues of mice were taken to measure the ratios of lung wet to dry weight (W/D). The bronchoalveolar lavage fluid of mice was collected to measure the levels of TNF-α, IL-6, and IL-1β by ELISA kit and to count the number of eosinophils (EOS), lymphocytes, neutrophils under light microscope. After HE staining, the pathological changes of lung tissues were observed and lung injury was scored. qRT-PCR method were used to determine the expression levels of miR-223 in lung tissues. Western blotting was used to determine the expression levels of NLRP3 protein in mouse lung tissues. Luciferase reporter assay was used to analyze the targeting relationship of miR-223 to NLRP3.@*RESULTS@#Compared with the control group, the lung W/D value, the lung injury score and the level of inflammatory factors in the bronchoalveolar lavage fluid were significantly increased in the model group (all P<0.05); the infiltration of inflammatory cells in the lung tissue was severe; the alveolar space was significantly increased; the alveolar wall was significantly thickened; the number of EOS, lymphocytes, and neutrophils in the bronchoalveolar lavage fluid was significantly increased (all P<0.05); the expression levels of miR-223 in lung tissue were significantly decreased (P<0.05); and the protein expression levels of NLRP3 were significantly increased (P<0.05). Compared with the model group, the W/D value of lungs, lung injury score, and levels of inflammatory factors in bronchoalveolar lavage fluid were significantly decreased in the chlorogenic acid group, the chlorogenic acid+miR-223 NC group, and the chlorogenic acid+miR-223 antagomir group (all P<0.05); lung tissues damage was alleviated; the numbers of EOS, lymphocytes, and neutrophils in bronchoalveolar lavage fluid were significantly decreased (all P<0.05); the expression levels of miR-223 in lung tissues were significantly increased (P<0.05); and the expression levels of NLRP3 protein were significantly decreased (P<0.05). Compared with the chlorogenic acid group, the lung W/D value, lung injury score, and inflammatory factor levels in the bronchoalveolar lavage fluid were significantly increased in the chlorogenic acid+miR-223 antagomir group (all P<0.05); lung tissue damage was aggravated; the number of EOS, lymphocytes and neutrophils in bronchoalveolar lavage fluid significantly increased (all P<0.05); the expression levels of miR-223 in lung tissues were significantly decreased (P<0.05); and the expression levels of NLRP3 protein were significantly increased (P<0.05). The results of luciferase reporter assay showed that miR-223 had a targeting relationship with NLRP3.@*CONCLUSIONS@#Chlorogenic acid may increase the level of miR-223, target the inhibition of NLRP3 expression, reduce LPS-induced inflammatory response in ALI mice, and alleviate pathological damage of lung tissues.

Objective:To determine the spiritual needs of shrinking man syndrome (SMS) in young and middle-aged patients, and to provide reference for determining targeted intervention plans.Methods:From May to July, 2021, 14 young and middle-aged patients with SMS who received hyperparathyroidism thermal ablation in the Interventional Medicine Department of China-Japan Friendship Hospital were selected by purpose sampling method. Qualitative research phenomenology was used to conduct semi-structured in-depth interviews, and the interview data were analyzed by Colaizzi 7-step analysis method.Results:There were 4 themes and 14 sub-themes: "understanding and self-acceptance of illness" (attribution to illness; disease uncertainty; acceptance and illness), "need for social support" (love and respect; connection and companionship; family support; medical support; patient support), "life value and sense of meaning" (life meaning and goal; self-esteem; religious belief), "self-actualization and transcendence" (hope for improvement; eager for miracles; realize your value).Conclusions:Medical staff should pay attention to the spiritual needs of young and middle-aged patients with SMS, and specifically meet their spiritual needs during diagnosis, treatment, nursing and follow-up, so as to improve the patients′ sense of life meaning and value, and help them to better survive with disease and return to society.

Effects of resilience on posttraumatic growth in patients with refractory secondary hyperparathyroidism: the mediating role of hope / 中国实用护理杂志

Objective:To investigate the mediating effect of hope on resilience and post traumatic growth (PTG) in patients with refractory secondary hyperparathyroidism (rSHPT).Methods:It was convenient to select rSHPT patients and non-refractory SHPT patients who received maintenance hemodialysis treatment in China-Japan Friendship Hospital from September 2018 to September 2021. Totally 495 patients with rSHPT and 1 295 patients with mild secondary hyperparathyroidism (SHPT) were surveyed by the Chinese Version of The Herth Hope Scale, the Chinese version of the Connor-Davidson Resilience Scale and the Post Traumatic Growth Rating Scale (PTGI). After matching according to the 1∶1 Propensity Score Matching (PSM), 436 cases were set in each of the two groups. The differences of hope, resilience and PTG scores between the two groups were compared. Pearson correlation analysis was used to analyze the correlation between hope, resilience and total score of PTG in rSHPT group. Regression analysis and SPSS Process mediation Model 4 were used to test the mediating effect of hope on resilience and PTG.Results:The hope score (32.16 ± 4.15), psychological resilience score (61.22 ± 14.38), and the PTG score (52.34 ± 18.92) of rSHPT patients was significantly lower than 33.41 ± 2.97 ( t=-5.72, P<0.05), 63.19 ± 7.25 ( t=-2.77, P<0.05), 57.95 ± 10.07 ( t=-6.34, P<0.05) of SHPT patients. There was a positive correlation between hope, resilience and PTG score ( r=0.671, 0.488, 0.523, all P<0.01). Regression analysis showed that resilience could positively predict PTG ( β=0.518, P<0.01). Psychological resilience positively predicted hope ( β=0.188, P<0.01). Resilience ( β=0.204, P =0.002) and hope ( β=1.442, P<0.01) could positively predict PTG. Hope played a partial mediating role in the relationship between resilience and PTG, and the mediating effect accounted for 60.23%. Conclusions:rSHPT patients generally had lower levels of hope, resilience and PTG. Resilience can affect PTG directly or indirectly through hope. Medical staff should improve the resilience and hope level of patients with rSHPT through positive psychological intervention measures, so as to enhance the positive promoting effect of psychological resilience on PTG.

Comparative study of air-charged urodynamic and water-filled urodynamic examinations of elderly patients with benign prostatic hyperplasia / 中华老年医学杂志

Objective:To assess whether air-charged urodynamic(ACC)can replace water-filled urodynamic(WFC)and the value of ACC for the diagnosis of benign prostatic hyperplasia(BPH)in these patients.Methods:In this prospective study, 27 male patients with BPH(aged 60-90 years)were randomly selected for WFC and ACC examinations during the same period to compare the values of urodynamic pressure parameters recorded for the two groups.Pressure values were compared using Bland-Altman plots and the paired sample t-test, and differences in abdominal pressure changes in the two groups were compared using the chi-square test. Results:Changes in WFC and ACC pressure values showed the same trends, but at the three points where data were recorded and compared, the mean abdominal pressure(Pabd), end of bladder filling pressure(Pves.fill)and maximum detrusor pressure(Pdet.void)were(25.3±8.5)cmH 2O(1 cmH 2O=0.098 kPa), (26.0±8.08.4)cmH 2O and(98.8±32.8)cmH 2O for WFC and(32.5, 5.5±5.3)cmH 2O, (32.6±5.0)cmH 2O and(95.3±36.3)cmH 2O for ACC, respectively, The pressure values of the two methods were significantly different( P<0.05). WFC pressure values were unstable, with 74.07%(20/27)showing a marked decrease during bladder filling, significantly different from those measured by ACC( P<0.001). Band-Altman plots illustrated high consistency between pressure values measured via WFC and ACC. Conclusions:The pressure measured by ACC does not represent that measured by WFC, suggesting a clinical need to establish standard reference data for ACC.The abdominal pressure instability measured by WFC may be one of the factors leading to different detrusor pressures from the two methods.The high consistency between pressure values from ACC and WFC indicates that the former can also be used to assess changes in bladder function in elderly BPH patients.

Suspension exercise training can improve walking and balance after thoracolumbar fracture and spinal cord injury / 中华物理医学与康复杂志

Objective:To explore the effect of suspension exercise training (SET) on the lumbar function and balance ability of patients with thoracolumbar fracture and spinal cord injury.Methods:Totally 64 patients with thoracolumbar fracture and spinalcord injury were randomly divided into a control group and an observation group, each of 32. Both groups received pedicle screw reduction with internal fixation and spinal dome decompression, followed by routine post-operative rehabilitation. In addition, the observation group performed double bridge and single leg suspension training and pelvic lift training. Everyone′s walking ability, spinal nerve functionality and balance were evaluated 3 days after the operation and 2 months after the training. Stride frequency, stride length and walking speed were observed. American Spinal Injury Association (ASIA) nerve function classifications were assigned. The trajectory length, trajectory included area and movement deviation of each subject′s center of gravity (CG) was recorded.Results:The average stride frequency, step length and walking speed of the observation group had all improved significantly after the intervention, and were significantly better than the control group′s averages at that point. This was also true of the proportion in ASIA neurological function grade D (65.63%), CG trajectory length and area, and the Romberg rate of deviation along the X-axis and Y-axis of the CG.Conclusion:SET training after pedicle screw reduction and internal fixation and spinal dome decompression can significantly improve the spinal nerve functioning of persons after a thoracolumbar fracture with incomplete spinal cord injury. It enhances their balance and walking ability. Such therapy is worthy of clinical promotion and application.

Combining scalp acupuncture with feedback can relieve post-stroke spasticity and paralysis of the lower extremities / 中华物理医学与康复杂志

Objective:To observe the effect of combining scalp acupuncture with feedback training on muscle tone, motor ability, plantar pressure distribution and joint range of motion of stroke survivors with lower limb spastic paralysis.Methods:A total of 212 stroke survivors were randomly divided into a combination group ( n=70), an exercise group ( n=70) and a scalp acupuncture group ( n=72) according to a random number table. All of the patients received routine medication and 120 minutes of rehabilitation training six days a week for 8 consecutive weeks. The rehabilitation training included guidance on good posture, posture change training, balance training and gait training. The scalp acupuncture and exercise groups were additionally provided with 40 minutes of scalp acupuncture and lower limb intelligent feedback training, while the combination group was given both. Muscle tension, balance and lower extremity movement were quantified before and after the training, and a gait evaluation system was used to detect the plantar pressure distribution on the affected side and the range of motion range of the lower limb joints during walking. Results:After the treatment, significant differences were observed in the average modified Ashworth scores, modified Berg scale scores, Fugl-Meyer lower extremity ratings and modified Barthel Index scores compared with before the treatment. The average scores of the combination group were then significantly better than those of the other two groups. The average load bearing ratios of the affected toes, metatarsal bones Ⅰ-V, medial arch, external arch, medial heel and external heel had improved significantly in all of the groups, with the improvement of the combination group again significantly greater than those of the other groups. The same pattern of improvement was observed in the groups′ average pelvic rotation angles, hip flexion angles, knee flexion angles and ankle dorsiflexion angles.Conclusion:Combining scalp acupuncture with intelligent feedback can significantly improve lower extremity functioning after a stroke. That should improve performance in the activities of daily living of stroke survivors.

We report here a human case of Taenia asiatica infection which was confirmed by genetic analyses in Dali, China. A patient was found to have symptoms of taeniasis with discharge of tapeworm proglottids. By sequencing of the mitochondrial cytochrome c oxidase subunit 1 (cox1) gene, we observed nucleotide sequence identity of 99% with T. asiatica and 96% with T. saginata. Using the cytochrome b (cytb) gene, 99% identity with T. asiatica and 96% identity with T. saginata were found. Our findings suggest that taeniasis of people in Dali, China may be mainly caused by T. asiatica.

The study of acoustically evoked short latency negative responses in normal guinea pigs / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To compare acoustically evoked short latency negative responses (ASNR) elicited from normal and profound hearing loss guinea pig ears and to confirm their vestibular nuclei origination.</p><p><b>METHODS</b>Forty healthy guinea pigs were employed in the experiment, which were randomly divided into the control group (8 subjects, 16 ears), the masking group (16 subjects, 32 ears) and the deafened group (16 subjects, 32 ears). Air conductive white noise was chosen for masking. Masking dilemma was avoidable by an appropriate 15 dB gap between stimulus and masking sound. Both the masking group and the deafened group were further divided into ASNR group and non-ASNR group based on the presence of ASNR. Electrolytic lesion was conducted to the vestibular nuclei, followed by ABR/ASNR recording. The lesioned brainstem slices were microscopically verified.</p><p><b>RESULTS</b>In the masking group, ASNR were present in 24 ears (75.0%, 24/32) and 12 ears (46.2%, 12/26) in deafened group, showing statistically higher presence rate for masking group (χ(2)=5.07, P=0.024). There were no significant differences for the ASNR threshold and latency between the masking ASNR group and the deafened ASNR group. For the two ASNR groups, electrolytic destruction to the vestibular nuclei subsequently eliminated the ASNR. Brainstem slice proved the accurate sites of electrolytic lesion.</p><p><b>CONCLUSION</b>Moderate white noise masking prevents hearing system potential overlap without affecting vestibular system, therefore, ASNR is successfully elicited in normal guinea pigs. Both ASNRs from normal and deafened guinea pigs are of similar natures and origination from, the vestibular nuclei.</p>

Analysis of different treatment for 78 cases of pancreatic pseudocyst / 中华内分泌外科杂志

Objective To analyze the different procedures and their clinical effects on treatment for pan-creatic pseudocyst( PPC) .Methods The management and outcome of 78 patients with PPC from Jan.2002 to Jun.2012 were retrospectively analyzed.Results 20 patients underwent conservative treatment and the pseudo-cysts absorbed spontaneously during follow up.Invasive procedures were performed in 58 cases, including percu-taneous catheter drainage in 3 cases with 1 postoperative pancreatic leakage and 1 postoperative pancreatic ab-scess;PPC external drainage in 5 cases with 2 postoperative pancreatic leakage and 1 postoperative bleeding;pancreatic pseudocyst stomach anastomosis in 15 cases with 1 postoperative gastrointestinal bleeding;Roux-en-Y cystjejunostomy in 29 cases with 2 gastrointestinal bleeding;cystduodenostomy in 2 cases;pancreatic pseudocyst excision in 2 cases with 1 postoperative pancreatic leakage; and laparoscopic cystogastrostomy in 2 cases.Con-clusions At present, there are various treatment options for pancreatic pseudocyst and it is necessary to choose treatment strategy according to patient's condition.Internal drainage is still the primary option of surgical proce-dures in treatment for pancreatic pseudocyst.
